While in bed you immediately mount your significant other and proceed to fart on their chest while holding them down under the covers. Their reaction to the act and the smell will send them into "exorcism" like convulsions and screaming.

Me: " After she embarrassed me at the party last night I had no other alternative retaliation but to give her The Exorcism while she was sleeping."
Bro:" Nah ah dude! You were drinking Guinness all night that must have turned her into a real Emily Rose!"
